deficiency
JOURNAL Science 340 (6136), 1106-1110 (2013)
PUBMED 23599266
REMARK GeneRIF: The crystal structure of the
alpha-TTP-phosphatidylinositol phosphates (PIPs) complex revealed
that the familial vitamin E deficiency-related arginine residues
interacted with phosphate groups of the PIPs and that the PIPs
binding caused the lid of the alpha-tocopherol-binding pocket to
open.

possibly, alpha -TTP is notonly involved in normal pregnancy, but
also in cases of pregnancy disorders with intense oxidative stress

COMMENT REVIEWED REFSEQ: This record has been curated by NCBI staff. The
reference sequence was derived from BC058000.1, BC041784.1 and
AC120042.3.
This sequence is a reference standard in the RefSeqGene project.
On Sep 20, 2006 this sequence version replaced gi:113420428.
Summary: This gene encodes a soluble protein that binds
alpha-tocopherol, a form of vitamin E, with high selectivity and
affinity. This protein plays an important role in regulating
vitamin E levels in the body by transporting vitamin E between
membrane vesicles and facilitating the secretion of vitamin E from
hepatocytes to circulating lipoproteins. Mutations in this gene
cause hereditary vitamin E deficiency (ataxia with vitamin E
deficiency, AVED) and retinitis pigmentosa. [provided by RefSeq,
Nov 2009].
Sequence Note: This RefSeq record was created from transcript and
genomic sequence data to make the sequence consistent with the
reference genome assembly. The genomic coordinates used for the
transcript record were based on transcript alignments.
Publication Note: This RefSeq record includes a subset of the
publications that are available for this gene. Please see the Gene
record to access additional publications.
